Trivia, insights & behind the scenes
THE iDOLM@STER pioneered the 'producer' self-insert model that dominates Japanese mobile gaming; this concert is essentially a shareholder meeting for 20 years of emotional investment.
Eriko Nakamura has voiced Haruka Amami since 2005 — her performance here spans nearly half her life, making this as much autobiography as character work.
